Spacetime Sandbox Theory

A speculative physical model in which spacetime is treated as a sandbox – a malleable, reversible, and reconfigurable environment where advanced agents can test physical laws, create pocket universes, or simulate alternate causal structures without permanent consequences. Unlike our apparently rigid spacetime, the sandbox version allows “what if” experiments at the cosmic scale. It often appears in discussions of computational physics and simulation hypothesis, but also as a metaphor for the freedom of theoretical exploration.

Example: “His proposal for a spacetime sandbox theory suggested that a Type III civilisation might create isolated laboratory regions where they could temporarily violate energy conservation for research – then reset.”
